This invention aims to rovide an improved carpet fastener' insta lation.

In the vdrawings which illustrate'a preferred embodiment of my inventionFig. '1 isa plan view of' a portion of a carpet or rug, a portion of theunderlyin floor and the fastening means (in dotte lines) for securinthecarpet to the floor; 4

Fig.I 3 isa plan view of :the stud unit before attachmentto a carpet;

gig. 4 is a side elevation of the stud unit; an

Fig. 5 is a section 'through the stud unit on the line 5-r5 Vof Fig. 3.

Referring to the drawings, I have shown a carpet fastener installationwhich includes fastening means ofvery simple and inexpensiveconstruction. p

Heretofore carpet fasteners usually ineludeda socket member and astud-member which had to be somewhat carefully aligned with each otherso as 'to be readily secured together without stretchinvP the carpet toany great extent. Such fasteners 1f not closely-.aligned required toogreat a stretch of the'fcarpet to ermit fastenin with the result thatone or lie other had to ge removed and repositioned to provide forbetter alignment. g

The stud member of the fastenin means illustrated in the drawings isshifta le'to a limitedextent in any transverse direction relative to thecarpet and ther' fore the combined -shiftability of any numbervoffast--v eners located in a given llneof strain on the carpet will permitalignment of the fastener elements wherev they could not be securedtogether without the shiftable feature of the stud. The shiftablemembers of the fastener may be secured to the floor but I prefer thatthe v shall be secured to the car t so that a p ain hole in the oor maysu ce a a socket element. V

The installation as illustratedv in Figs. l and 2 includes-a carpet 1,carrying a pluralit of shiftablestud units (only one of which is shown)and a floor 2 (which may be the floor boards, sills o r other portionsof an automobile underlying the carpet).

The stud unit includes a casing part 3 and a stud art 4 each formed froma sin lc piece o metal and secured in assemb ed relation with eachother' as illustrated in which is pressed a head 10 and a relatively Iv9 as illustrated in Figs. 3, 4 and 5. The casing has a flat faceportion` 5' presenting an aperture 5 throu h f which a portion of thestud may protru e, an annular wall 6, a plurality of attaching prongs 7extending upwardly from the wall and a plurality of ears 8 extendinginwardly from the wall generally parallel with and spaced away from theface portion 5. The stud part includes a flat base portion 9 from longneck 11. The head and neck are made Ycontractible and expansible byslits 12 which-v of the head to the base ig. 2..

When the .parts of the stud unit are as'- sembled the ears 8 of thecasing overlie the base 9 of the stud to prevent axial movement of thestud part relative to the casing and lthe head and neck extend throughthe aperture 5 as illustrated in Fig. 5. Trans- 75 Verse shiftingmovement of the stud in any direction relative to the. socket ispermitted because the base 9 of the stud is smallerin diameter than thespace enclosed by the wall 6 of the casing and because the neck 11 ofthe stud is smaller in diameter than the diameter of the aperture 5**inthe face portion 5 of the casing which the head and neck of the stuppass.

The stud member may be secured to the carpet 1 in any suitable mannerbut I referto securefit to the under side thereo by forcing the prongs 7through the web of the carpet and bending them outwardly and downwardlyfrom thev'vall 6 to hook over the warp and weft threads of the carpet asillustrated in Fig. 2. v The floor 2 may be of wood or of metal as shownin the drawings and thek only socket necessary is a plain hole oraperture 13 through the floor about the diameter of the neck ofthe studasshown in `Fig.`2.

When securing the carpet 1 to the floor 2 extend `from the to the studmember may be shifted so "as to with and carryin of parts and evenchanges in the mode of operation maybe made without de arting from thescope of my invention w ich is best defined in the following claims.

Claims:

1. A carpet fastener installation comprising, in combination, a carpet,a casing secured to said carpet and a stud member assembled with andprojecting from said casing, said stud shiftable in any transversedirection relative to said casing for alignment with a cooperatingsocket.

2. A carpet fastener installation comprising, in combination, a carpet,a casing secured to the under side of said carpet, a resilient studmember assembled with and shiftable in any transverse direction relativeto said casing, and a floor presenting a stud receiving aperture offixed dimensions for receiving said resilient stud member thereby tosecure the carpet in place upon the iioor.

3. A carpet fastener installation comprising, in combination, a carpet,a casing'member and a stud member, said casing member presenting aplurality of attaching prongs ooked over the warp and' weft threads ofsaid carpet to secure said casing to the under side of the carpet andmeans for holding said stud in assembly Withsaid casing while permittingsubstantial transverse shifting movement of said stud relative to thecasing for alignment With a cooperatin fixed socket.

4. A car et fastener insta lation comprising, in com ination, a car et,a casing, and a contractible and expansi le stud assembled with saidcasing and shiftable transversely relative thereto, said casingpresenting a plurality of outwardly curved attaching pron hooked overthe warp and weft threads of the carpet to secure said .casing and saidstud to the underside thereof.

5. A carpet fastener installation including separable fastening meanscomprising stud and socket elements one of which is shiftable relativeto the other for alignment theremediums adapted to be secured Ytogethery the fastener elements, one of said fastener elements including a partfor attachment to one of the carrying mediums and a second part forcooperation With the other fastener element, said second part having aportion held by said attaching part and said ortion being of smallerdiameter than said attaching art so as to be shiftable transversely inall irections in the first-mentioned part, thereby to provide for thealignment of the stud and socket elements.

6. A carpet fastener installation including ,a carpet and a stud unitattached to the carpet for engagement with cooperating fastener means toposition the Carpet relative to a part which presents said cooperatingfastener means, said stud unit including a casing part presentingattaching means extending therefrom to secure the casing to the fastenersupport and a stud part having a base assembled with said casin part anda head and neck-extending thererom in the opposite direction from saidattaching means, said base bein of smaller diameter than said casing angbeing transversly shiftable in any direction in saidcasing.

7. A stud unit including a one-piece casing part having attaching prongsextending outwardly therefrom for securing it to a suitable support anda stud member assembled with the casing, said stud member having a baseheld by said casing, said base being smaller'in diameter than saidcasing so as to be shiftable transversely in any direction in saidcasing and presenting a resilient head which extends from the casing atthe opposite side thereof from which the attaching prongs extend.

8. A carpet fastener installation includin a car et, a stud part locatedat the under si e of t e carpet and an attaching part assembled with thestud to provide a'single unit for securing said stud to the carpet, saidstud part having a base heid by said attaching part and having itsperiphery spaced from the attaching part, said base being shiftabletransversely in all directions relative to said attaching part.

In testimony whereof, I have signed my name to this specification.
